Radeon R9 M375 vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which uses a 14 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this card. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 550 should in theory be quite a bit superior to the Radeon R9 M375 in general. (explain)

Radeon RX 550		114688 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 79488 (226%)

Texel Rate

The Radeon R9 M375 is a little bit (about 15%) more effective at texture filtering than the Radeon RX 550. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 5400 (15%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 550 is superior to the Radeon R9 M375, not by a very large margin though. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 1360 (8%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
